Abstract

PURPOSE: To catch dust without damaging a third dust collecting part as a paper packing filter by arranging a suction opening for sucking dust from a first dust collecting part to a second dust collecting part and a connecting opening for connecting the second dust collecting part to the third dust collecting part in a manner such that the connecting opening is present at a position higher than that of the suction opening and providing the second dust collecting part with a partitioning plate. CONSTITUTION: An electric cleaner 1 comprises in the lower part of a body 2 thereof a rotating brush 3 and a first dust collecting part 4 covering the rotating brush 3 and having a discharge opening 5 in the upper part thereof. The discharge opening 5 of the first dust collecting part 4 is connected to a suction opening 8 of a second dust collecting part 6 through a hose 7. A first connecting opening 9 of the second dust collecting part 6 is formed at a position slightly higher than that of the suction opening 8 of the second dust collecting part 6. The first connecting opening 9 is connected to a second connecting opening 12 of a third dust collecting part 10 through a hose 11. The second dust collecting part 6 contains a partitioning plate having a width smaller than the total width the second dust collecting part 6 and having one end fixed to the second dust collecting part 6 just below the suction opening 8 and the other end fixed to the second dust collecting part 6 below the first connecting opening 9. Lightweight dust will not be stirred up in the second dust collecting part 6.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic cleaner for cleaning a traveling road surface with a rotating brush disposed in a lower portion of a vehicle body and rotating in a direction perpendicular to the traveling road surface.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 3, a rotary brush 3 disposed in the lower portion of a vehicle body and rotating in a direction perpendicular to a traveling road surface sweeps dust to a first dust collecting portion 4 and The second dust collecting part 20 and the third dust collecting part 10 for lightweight dust.
In the automatic vacuum cleaner 1 that cleans the traveling road surface by sucking into
The suction port 21 from the first dust collecting portion 4 to the second dust collecting portion 20 and the second
The second dust collecting portion 20 to the third dust collecting portion 1 are arranged at substantially the same height as the connection port 15 from the dust collecting portion 20 to the third dust collecting portion 10.
The filter 15 is provided on the second dust collecting portion 20 side of the connection port 15 to 0.
It was configured to be attached.

[0003]

Conventionally, as described above, the suction port to the first dust collecting part and the second dust collecting part and the connection port from the second dust collecting part to the third dust collecting part are provided. The filters are installed at almost the same height, and the filter is attached to the second dust collecting part side of the connection port from the second dust collecting part to the third dust collecting part. There was a problem that the covering and suction ability was lowered and sufficient cleaning was not possible. The present invention has been devised to solve the above problems.

[0004]

SUMMARY OF THE INVENTION The present invention is a rotary brush disposed in a lower part of a vehicle body and rotating in a direction perpendicular to a traveling road surface. In an automatic cleaner that cleans a traveling road surface by sucking into the dust collecting portion and the third dust collecting portion, a suction port from the first dust collecting portion to the second dust collecting portion and a second dust collecting portion to the third dust collecting portion. And the lower part of the suction port from the first dust collecting part to the second dust collecting part, with the positional relationship of the connection port to the second dust collecting part to the third dust collecting part being above the connection port to the third dust collecting part. The above problem is solved by providing a partition plate for connecting the second dust collecting portion and the lower portion of the connection port to the third dust collecting portion to the second dust collecting portion.

[0005]

By providing the partition plate, dust is collected in the third dust collecting portion without any obstacle, and in the case of large dust, the wall below the connection port between the second dust collecting portion and the third dust collecting portion In connection with
From the top of the partition plate to the inside of the second dust collecting part, large dust does not block the connection port, so it can maintain good air flow,
Moreover, since large dust is not sucked into the third dust collecting portion, the number of times the paper pack filter used as the third dust collecting portion is replaced is reduced.

EXAMPLE An example of the present invention will be described with reference to FIG.
FIG. 1 is a side view of an automatic cleaner used in the present invention, where 1 is a main body of the automatic cleaner, 2 is a vehicle body of the automatic cleaner 1, and 3 is a vehicle body 2.
A rotating brush 4 provided in the lower part of the rotating body which rotates in a direction perpendicular to the traveling road surface, covers a rotating brush 3, and has a first dust collecting portion at which a discharge port 5 is formed at one place, and 6 is a first dust collecting portion. The second dust collecting portion 8 connected to the discharge port 5 of the dust collecting portion 4 by the hose 7,
Is a suction port of the second dust collecting unit 6 connected to the discharge port 5 of the first dust collecting unit 4 by the hose 7, and 9 is a second collecting unit formed slightly above the suction port of the second dust collecting unit 6. The first connection port 10 of the dust part 6 is a third dust collection part which is connected to the first connection port 9 of the second dust collection part 6 via the hose 11, and 12 is the first connection part of the second dust collection part 6. Mouth 9
The second of the third dust collecting portion 10 connected to the second dust collecting portion 10 via the hose 11.
As shown in FIG. 2, the connection port 13 is a partition plate having a width narrower than the entire width of the second dust collecting part 6, and both ends of the partition plate 13 are located immediately below the suction port 8 of the second dust collecting part 6 and the first part. 1 is fixed to the lower part of the connection port 9.

[0007]

As described above, the present invention provides an automatic cleaner for cleaning a traveling road surface with a rotating brush which is arranged in the lower portion of the vehicle body and rotates in a direction perpendicular to the traveling road surface. The second dust collecting portion and the vacuum motor are connected to each other in the vehicle body by setting the connection port between the second dust collecting portion and the third dust collecting portion above the suction port of the second dust collecting portion. By disposing the partition plate and fixing the partition plate to the lower part of the suction port of the second dust collecting part, the lower part of the first connecting port, and the lower part of the first connecting port, the second collecting part can be installed in the second collecting part. The air flow from the suction port of the dust part toward the connection port to the third dust collecting part is formed without any disturbance, and the rising of the lightweight dust stored in the second dust collecting part is prevented, and the third dust collecting part is Small and lightweight dust is collected without any obstacles, and large dust is collected in the 2nd dust collection part, paper pack The frequency of replacement of the Iruta is reduced.
